Ramatuelle.
Pampelonne, Loulou, and the back-road vineyards.
Ramatuelle is the postal code of Pampelonne beach. Most of the beach clubs you've heard of sit on the Boulevard Patch: Club 55, Loulou, Bagatelle, Nikki Beach, Verde, Shellona, Casa Amor, La Réserve à la Plage, Kinugawa.
The village of Ramatuelle itself is up the hill, half an hour from the beach by car in August. Les Moulins de Ramatuelle is a refined Provençal alternative when Kinugawa is full.
